According to the formula below:
$$F = \phi * I *
as \phi representing the fluorescence efficiency of the tested substance, \CapI representing the intensity of light inserted by the testing machine “Molecular Devices FilterMax F3” per second per squared centimeter, \epsilon representing the fluorescence Molar Absorption Coefficient of the fluorescence substance, and with c representing the the concentration of the sample and \l representing the thickness of the samples. As the setting of the experiment goes, these factors except the concentration and the thickness of the samples are merely the same - which doesn’t count anymore. The relationship between the Fluorescence intensity and the concentration of the sample can be viewed as linear.
As the thickness of the samples differs significantly less than the concentration of the sample does, we don't consider the thickness of the sample a determinant factor.
We therefore predicted that the higher concentration the sample gets, the higher the fluorescence intensity the result might shows.
As the design of our project shows: the concentration of the fluorescence substance have to correspond to the existence of both the bio-marker miR-155 and bio-marker miR-10b.
So the amount of the fluorescence substance should not differ when the amount of both bio-markers remains the same and should be linear to the amount of both bio-markers when both added in the experiment.
Concentration curve using partially purified wtGFP protein. Dilutions of wtGFP protein were made using 10 mM Tris, 10 mM EDTA buffer as the diluent. Samples were read using an FL600 fluorescence plate reader with reader function controlled by KC4 data reduction software on an external PC. Fluorescence was determined using a 400 nm, 30 nm bandpass excitation filter and a 508 nm, 20 nm bandpass emission filter with an instrument sensitivity setting of 175.【1】
